 ===========================================================
 
Rivers and canals
Where water finds it's way
as wel as fish, humans, boats and beasts, animals
where it exceeds, crosses, meanders, evades


natural riverbeds have their own dynamics
human intervention modifies this
yet there are processes that do not abide these adjustments
or these choices have unexpected consequences

We are going to follow a few of these trajectories, for as long as we can
- because they contain a lot of information
- because of the random factor
- because these structures are bypassed of used unexpectedly or even improperly (what is proper/improper anyway)
- because you run into surprises

link with data
in computing - The physical paths are determined - infrastructure
what you can do on them/with them is pretty much predetermined
we are interested in stepping over the lines (Dutch - buiten de lijntjes kleuren - colour outside of the lines?)- reversing processes - contaminating
the unexpected - the improper?


==========================================================================


Trajectory
=========
- Take the metro to Ceria Coovi
- Walk along the Chaussee the Mons 
- go into the Vogelzang nature reserve on the left 
- walk to the end of it
- take one step in Negenmanneke - Flanders, turn and proceed to the Zuunstraat - Rue de Zuen towards the canal

- For a large part we followed this trajectory, of this walk:

Part one - the inbetween

We followed the maps in reverse order

Part 2 Canal (s)
=================
1827 - 1832 - canal is dug - canal charleroi-Brussels
what we think to be one canal, is actually at least two
connects to 
    Canal du Centre (Seneffe)
    seacanal Brussel-Schelde (escaut) (Brussel)
    de Samber (Charleroi)

Ronquières Inclined Plane (Plan incliné de Ronquières ) replaces 14 locks
The Ronquières Inclined Plane has a length of 1,432 metres (4,698 ft) and lifts boats through 67.73 metres (222.2 ft)[2] vertically. It consists of two large caissons mounted on rails. Each caisson measures 91 metres (299 ft) long by 12 metres (39 ft) wide and has a water depth between 3 and 3.70 metres (9.8 and 12.1 ft). It can carry one boat of 1,350 tonnes or many smaller boats within the same limits.
Each caisson has a 5,200-tonne counterweight running in the trough below the rails, which permits the caisson to be moved independently of the other.[2] Each caisson is pulled by 8 cables wound by winches located at the top end of the inclined plane. Each cable is 1,480 metres (4,860 ft) long.
Each caisson can be moved between the two canal levels at a speed of 1.2 metres per second (3.9 ft/s), taking about 22 minutes.
It takes 50 minutes in total to pass through the 1,800 metres (5,900 ft) of the entire structure, including the raised canal bridge at the top end.[2]

- fisherman (only since 2010) --> types of fish
-- cyprinids = voorn = certains types de carpe
-- common bream = brasem = breme commune
-- northern pike = snoek = grand brochet
-- zander = snoekbaars = sandre
-- european eal = paling = anguille d'europe
-- ide==orfe = de winde = ide melanote
- highspeedcyclists --> speedlimit (thus minister weyts) = 30km per hour
- leisure cyclists
- walking
- industry stuff in the boats (city as the mine of the future)

we pass by the Marina - sports & restaurant

part 3 - overflow
==================
% GRAFT: overflow, transgression
In software, a stack overflow occurs if the stack pointer exceeds the stack bound. The call stack may consist of a limited amount of address space, often determined at the start of the program. The size of the call stack depends on many factors, including the programming language, machine architecture, multi-threading, and amount of available memory. When a program attempts to use more space than is available on the call stack (that is, when it attempts to access memory beyond the call stack's bounds, which is essentially a buffer overflow), the stack is said to overflow, typically resulting in a program crash

- too much water
- meet the Zenne
- again free space --> gardens
- picturesque picknick table in between industry zones and the railway line
- look at the Zenne fork (go over - and spot the industry Zone)

% GRAFT: overflow, interaction
What water sources interact with the canal and the river?

part 4 - the island
=======================
- old textile industry
- Italian restaurant
- wool mill Daoust --> Aa mills
- eerie

part 5 - traffic - in and out of pipes
========================================
- main entry point to get into Brussels (and out of it)
- daily traffic jams
- Zenne at gas station - http://www.openstreetmap.org/?mlat=50.82284&mlon=4.30773#map=19/50.82284/4.30773&layers=N
- zone pipi - yet fresh prunes and grapes - remnant of the past?
- industry again
- cross paepsem

follow till we can't anymore? or go back?

part 6 - going underground
===========================
Ending in a collective garden: http://www.openstreetmap.org/?mlat=50.82414&mlon=4.31678#map=18/50.82414/4.31678&layers=N
